Devon Erickson, 18, and Maya McKinney, 16, were both scheduled to appear in court Wednesday at 10 a.m. for their formal charges hearing. McKinney's lawyer said the suspect uses the "he" pronoun and goes by the first name Alec, though court documents identified him as Maya.

McKinney's status hearing is scheduled for June 14. The 16-year-old will be charged as an adult in district court.

The only difference between the two suspects' charges are related to a firearm. Erickson is charged with providing a handgun to a juvenile and McKinney is charged with possession of a handgun by a juvenile.

The filing of charges for both suspects was originally planned for May 10, but was pushed to Wednesday.

In a press conference after court, District Attorney George Brauchler said it is too premature to comment on the death penalty.

Brauchler said he couldn't imagine a more difficult situation than what Castillo's parents are going through.

"They are a very strong couple," he said. "It would have been easy for them to say, 'I’m not going to make it to court today because in less than two hours we’re about to have a memorial for our son.'"
